How this service works
Call when an agent needs stylesheet hrefs via link[rel='stylesheet'] from a public page or HTML (SSRF-safe). Send JSON fields html (string). Exact $0.002 USDC on Base. Try unpaid POST /v1/sandbox/css-link-stylesheet first.
Output
Returns a list of href attribute values from all link[rel='stylesheet'] elements found in the provided URL's page or raw HTML. Each entry is a stylesheet URL (absolute or relative) as it appears in the HTML source.
Example use cases
Audit page stylesheet dependencies
“Fetch all the stylesheet links from https://mysite.com/landing so I can see which CSS files the page is loading.”
Extract CSS links from pasted HTML
“I have this HTML snippet — can you pull out every link[rel='stylesheet'] href from it? Here's the HTML: <html><head><link rel='stylesheet' href='/css/main.css'><link rel='stylesheet' href='https://cdn.example.com/bootstrap.css'></head></html>”
Compare stylesheets across environments
“Get the list of CSS stylesheet hrefs from https://staging.myapp.io/home so I can compare them against what's on production.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-link-stylesheet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate all CSS stylesheets linked in a webpage or HTML fragment, especially in automated pipelines auditing frontend asset loading, performing dependency analysis, or diffing stylesheet configurations across environments. Prefer the free sandbox endpoint (/v1/sandbox/css-link-stylesheet) for development and testing to avoid the $0.002 USDC charge.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty list
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- HTML input exceeds 200,000 character limit — request rejected
- No stylesheet link elements present in the page — returns empty list
- Malformed HTML may cause parser to miss some link elements
